zip ties and fluke mate! thats all that it takes... if only that was true...
in fairness to the truck, i just fitted whatever upgrades i felt i needed and it more or less worked. i have read of other .28s in funfactors that are a lot more stock than mine and are running fine. its easy enough to get a SH.28 cheap on ebay and the cen .21 engine mounts, just need an easily made manifold and there u go! it was antwar wasnt it who had a .28 in his? think there was at least one more from rcu too, and of course a few .21s - so yea, not bad really for what they are.
the os 18 will give u a lot less trouble and more useable performance than the .28 tho - in case u werent sure...
